Abstract Aiming at the problem caused by strong coupling, large interference and strong nonlinearity of aerospace morphing vehicle in hypersonic flight environment, a dynamic inversionbased attitude control method is proposed. The plant model is built using Kane method applicable to multirigidbody modeling. Firstly, the dynamic inversion controller is designed based on the fixed configuration, and the attitude control stability in nominal state is validated by simulation under the condition of no unstable internal dynamics existing. And then, the model and parameter changes in the variable shape process are regarded as interference, and the ESO (extended state observer) is used for observation compensation to complete the stable transitional connection control. Finally, the correctness of the transitional connection control algorithm is analyzed through simulation.
